Trophic resources are an important control governing carbonate production. Though this importance has long been recognized, no calibration exists to quantitatively compare biogenic assemblages within trophic resource fields. This study presents a field calibration of carbonate producers in a range of settings against high-resolution in situ measurements of nutrients, temperature and salinity. With its latitudinal extent from 30°to 23°N, the Gulf of California, Mexico, spans the warm-temperate realm and encompasses nutrient regimes from oligo-mesotrophic in the south to eutrophic in the north. Accordingly, from south to north carbonates are characterized by: (i) coral-dominated shallow carbonate factories (5-20 m water depth) with average sea-surface temperatures of 25°C (min. 18°C, max. 31°C), average salinities of 35AE06& and average chlorophyll a levels, which are a proxy for nutrients, of 0AE25 mg Chl a m )3 (max. 0AE48, min. 0AE1). (ii) Red algal-dominated subtidal to inner-shelf carbonate formation (10-25 m) in the central Gulf of California exhibiting average temperatures of 23°C (min. 18°C, max. 30°C), average salinities of 35AE25&, and average Chl a levels of 0AE71 Chl a m )3 (max. 5AE62, min. 0). (iii) Molluskan bryozoan-rich inner to outer shelf factories in the northern Gulf of California (20-50 m) with average sea surface temperatures of only 20°C (min. 13°C, max 29°C), average salinities of 35AE01&, and average contents of 2AE2 mg Chl a m )3 (max. 8AE38, min. 0). By calibrating sedimentological data with in situ measured oceanographic information in different environments, the response of carbonate producers to environmental parameters was established and extrapolated to carbonates on a global scale. The results demonstrate the importance of recognizing and quantifying trophic resources as a dominant control determining the biogenic composition and facies character of both modern and fossil carbonates.

Research suggests that the relationship between resilience and substance use is a non-linear and multifactorial psychological process. Surprisingly, sensory processing is rarely mentioned as a variable associated with this phenomenon. In this study, we investigated the relationship between resilience, sensory processing, attitudes and consumption behaviors for alcohol, tobacco and other psychoactive substances. For this, we used four instruments: Adult / Adolescent Sensory Profile; Resilience Scale; Attitudes scales; Tobacco, Alcohol and Other Drug Use Scale. The sample consisted of 340 healthy adult participants, of whom 261 (76.8%) were women and 79 (23.2%) men. As for chronological age, the youngest person was 18 and the oldest was 76 years (M = 39; DP = 11). Sensory processing was associated with the intake behaviors and attitudes. Sensory imbalances appeared to be implicated in decreased resilience.

Relações entre suporte social, autorregulação e consumo de outras substâncias em adultos portuguesesResumo. Neste estudo, investigaram-se as relações entre suporte social percebido, auto-regulação e comportamentos de consumo de álcool, tabaco e outras substâncias psicoactivas. A amostra foi constituída por 340 participantes. O suporte social correlacionou-se favoravelmente com a auto-regulação, mas somente na vertente de satisfação com o apoio social é que se observou esta tendência de forma evidente. O número de figuras de apoio diferenciou-se significativamente com o uso de tabaco, o que sugere o âmbito afiliativo de algumas substâncias psicoactivas. Nesse sentido, o uso de tabaco pode estar associado a uma rede social mais ampla, mas não com a qualidade do suporte social.Palavras chave. Suporte social, autorregulação, comportamentos de uso, tabaco, outras substâncias.Abstract. In this study the relationships between perceived social support, self-regulation and consuming behaviors of tobacco and other psychoactive substances we investigated. The sample consisted of 340 adult participants. Social support correlated positively with self-regulation, but was solely in the aspect of satisfaction with social support that this trend was noted clearly. The number of support providers differed considerably with the use of tobacco, which suggests the affiliative scope of some psychoactive substances. Accordingly, the use of tobacco may be associated with a larger social network, but not with the quality of social support.
